Wheel-thrown stoneware "ball mug" with my signature ergonomic single finger handle... super comfy. 16 oz. stoneware tripod mug with a super comfortable two finger handle. These unique "ball cups" are perched atop a tripod set of clay balls which gives them a quirky attitude while maintaining their functional stability. Glazed turquoise inside and at the feet, the exterior is satin grey with a zig zag stripe, and has the look and feel of polished river stones. Food, dishwasher, and *microwave safe. 4 inches tall * This stoneware contains red iron which can heat up in a microwave causing hot handles and in rare cases, cracking. 20-30 second to reheat coffee is typically fine.
